Basic scientific achievements

1. The initial free radical processes and the chain photo- and thermo-reactions of primary radicals have been determined during the mechanical destruction of proteins. It has been shown that the initial act during the mechanical destruction of proteins is hemolytic breakdown of Calpa-C bonds (1982-1996).

2. Created a new "Site-Directed Tryptophan Fluorescence" (SDTF) method to determine the three-dimensional solution structure of proteins (1997, 2001).

3. The evidence of a scavenging function of tear lipocalin to remove lipids from the human corneal surface (1999, 2005)

4. Tertiary solution structure of the protein called tear lipocalin has been resolved by SDTF that subsequently confirmed by the X-ray analysis of the protein crystal (2005).

5. The ligand binding mechanism, orientation, dynamics and distribution of ligand position inside the cavity of the protein tear lipocalin have been elucidated by SDTF and Site-Directed Spin Labeling methods (2000-2010).

6. We have demonstrated that SDTF provides a promising approach to the study of the solution structure of proteins, as well as pH-dependent conformational dynamics, that is highly complementary

to structural methods such as crystallography. The SDTF method demonstrated that the protonation states of the residues around position 28 modulate conformational switches of the AB loop relevant to ligand binding. (2010).

7.  The conserved disulfide bond that links the hairpin CD to the C-terminus may be functionally relevant to all members of the lipocalin family. Deletion of the disulfide bond alters the binding function of the lipocalins in both ligand- and protein-specific manners. (2011)

8. Created a new "Site Directed Circular Dichroism" method to study conformational changes in proteins and demonstrated the advantage of low temperature measurements (2008, 2014).

9. "Cation-pi" interactions in proteins that belong to the lipocaline family have been analyzed to show their structural-functional character (2012)

10. A simple model-free method was developed for direct assessment fluorescent ligand binding by linear spectral summation (2014).

11. In order to evaluate the nearest side chains in proteins, we  proposed a method of "double tryptophan exciton" probe that was applied to tear lipocalin (2015)

12. SERS (surface enhanced Raman spectroscopy)  investigation for whole human blood on a nanostructured ZnO surface indicated that despite the moderate enhancement (20–30 fold), all spectral components of the blood demonstrated in regular Raman are detected in SERS on ZnO. Moreover, SERS on ZnO identifies some components of the blood that are not easily accessible to regular Raman spectroscopy. It has been shown that SERS on ZnO is a valuable tool to investigate the whole blood for diagnosis of various human diseases (2015-2016)
